Article
Open AccessThis paper presents a novel methodology for mesoscale‐to‐microscale downscaling of near‐surface wind fields. The model chain consists on the Weather Research and Forecast mesoscale model and the Alya‐CFDWind microscale ... -
A wind-lidar buoy for offshore wind measurements: first commissioning test-phase results
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Conference lecture
Restricted access - publisher's policyThis paper presents the development of a new commercial floating lidar system aimed to measure the wind resource and other environmental variables at candidate wind farm locations. This work describes this new lidar system ... -
Active current control in wind power plants during grid faults
(2010-11)
Article
Restricted access - publisher's policyModern wind power plants are required and designed to ride through faults in electrical networks, subject to fault clearing. Wind turbine fault current contribution is required from most countries with a high amount of ... -
